When it comes to tuning the Toyota GR Yaris or GR Corolla, compromises are inappropriate. These models are designed for drive, sharp turns and real driving pleasure. But even these “hot” hatches have a weakness — an insufficiently powerful intercooling system. However, it is this that becomes especially significant when it comes to tuning, track days or active driving in the summer.
That’s why we’re introducing the CSF Stepped-Core intercooler, developed in collaboration with Jackson Racing. It’s the largest and most efficient plug-and-play intercooler available today for the GR platform. These intercoolers are now available for order at ATOMIC‑SHOP Ukraine.
Designed for the most demanding GR projects
This intercooler is built from the ground up using 3D scanning and part prototyping to ensure a perfect fit and maximum performance without the need for cutting or welding.
Thanks to the stepped Tube & Fin design, the intercooler provides:
- Up to 45% more internal volume compared to the original
- Up to 73% more cooling area
- Faster cooling of the intake air
- Less thermal loads and more stable power
Confirmed by MotoIQ tests: intake air temperature is significantly lower even after several aggressive accelerations.
Built for the track. Reliable for the road.
This is not just an aesthetic upgrade. This is the latest motorsport technology aimed at maximizing the advantages of the GR Yaris / GR Corolla models:
- Fully TIG-welded aluminum body
- No plastic or rivets — just metal
- 2.5 inch (63.5 mm) nozzles — for greater airflow
- Motorsport-grade silicone hoses and clamps included
- Each intercooler is leak and pressure tested
- Installed using the plug-and-play principle
-
Backed by a 2-year manufacturer's warranty
You only need to trim the stock air duct a little — everything else is bolt-on.
Silver or Black — choose your style
- Silver finish: Toyota GR Stepped-Core Intercooler — #8285
- Black Coating: Toyota GR Stepped-Core Intercooler — #8285B
Both versions of the intercooler are equally effective, the only difference is in appearance. So choose what suits you best.
